Results show that the specific maximum weight loss rate can be used as a commonality parameter to evaluate and distinguish the reactivity of different coal and char, and that the heating rate selected in TGA experiment has no effect on the judgment.

• 结果表明，最大比失重速率作为比较物质反应性的判据具有一定的通用性，能够较好地区分不同煤焦之间的反应性；热天平试验升温速率对判断结果没有影响。
